Re: 40th anniversary of the blizzard of ’78

Heh! Reading the comments takes me back to the winter of '49. I was just a boy of 10, but I have vivid memories of the mounded snow and prolonged cold. Roads were closed, with living drawn to a slow pace. That, of course, was in the Salt Lake Valley, in Utah, but I think it was much wider spread tha...

Re: Delta 11" Lathe

If the bushings in question are the typical Oilite type, the OD may well be much larger than the target diameter. They make them overslzed, but are the desired size when pressed in the respective hole. If the OD of the bearing is altered, the resulting bore will be too loose. Rule of thumb for a pre...

Re: Unknown drill chuck

Wahlstrom quck change drill chuck. Very nice accessory, assuming one is doing production work with a single spindle. They are fast and easy to use, and grip very well. They do not operate in reverse, however, so they are limited to right hand rotation. Reversing releases the grip. They are four jaw ...

You'll hear a lot of the just buy old American iron and be happy arguments , I can agree with that whole heartedly if you know enough to properly evaluate a machine tool .
Very nicely stated!

Re: Super Scale

It would not be necessary for one to purchase the business, as new molds (dies) can be remade. What's important to success is the mindset of the individual, which would require thinking in keeping with that which was displayed by Barry. His products are what they are because he was a stickler for qu...

Re: Carbide Insert Speeds and Feeds

Not a dumb question at all. HR made holders for inserts that were precision ground. The holder in question accepts a modified triangle insert, ground with positive rake. Bear in mind, this holder is from about 1970, and I've been away from commercial machining since 1983, so I'm not up to date on wh...

Re: Boiler stays and heat expansion

I should leave this response to those who have expert knowledge, but the idea of having opposing flat surfaces not supported by stays makes no sense. Keep in mind, the pressure inside a boiler accumulates. It's measured as pounds per square inch--so if you have ten square inches and the boiler press...

Re: Rebuilding(?) a worn out lathe.

I don't know what things may need replacing, but the fact that the bed is flame hardened is in your favor, as a hardened bed is much slower to wear. The negative aspect is that it may not display wear in the way you might expect, forming ridges, for example. Wear may be gentle, over a long area, so ...

Re: Railroad supply switch Engine

Sorry, I'm no help with evaluating your engine, but I would like to make a couple comments that all readers need to consider. Please understand this message is not directed towards you, but readers in general. Posting pictures that large isn't well received by this board. It makes no sense to post s...

Re: Rebuilding(?) a worn out lathe.

Please don't condemn me cause I paint a lathe or whatever, One should not be condemned for painting a machine tool, as that decision is very personal, and can be done for the right reason. Some folks like their machines to look pristine, and there's nothing wrong with that. However, reckless use of...

Re: Does anyone recognize this lathe?

Perfectly normal. It takes a lot of experience for machines to be operated without error, but one should see improvement as time goes on. You get to the point where there's not a question about the end results---you know things will be correct, and when they're not, it's a total surprise. I used to ...
